It is very much reminiscent of Fairy Tail for most of the characters. Asta and Natsu both are very head strong and impulsive, and really are only 'smart' when they are in a middle of a life or death battle. There are multiple connections to characters that are similar or about the same character style, not just Asta and Natsu. But the whole 'friendship is power' and 'I will never and cannot give up' attitudes in this show are EXTREMELY similar to Fairy Tail.

Only based off of the first few episodes, but these two anime's give me the same kind of vibe. They are both based around an inn who takes care of godlike or mythical creatures. There are some differences like Konohana Kitan is all girls and they are taking care of the maintenance of the inn, which Kakuriyo doesn't have the MC doing that. And Konohana seems a little more light-hearted and fun while teaching some morals/lessons in a comedic or sweet way which I have not seen exactly that it Kakuriyo. Granted it is only the like second or third episode. Overall I felt a similarity vibe with these two anime, and hope others do too, and hope this is helpful :)
